DISINFECTING AND DEODORIZING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 660, 543, dated October 23, 1900.

Application filed December 21, 1899- Serial No. 741,174. KNO modeL To all whom it may concern:

Be it known that I, OLAUs FREESE, residing in the borough of Manhattan, in the city, county, and State of NeWYork, have invented certain Improvements in Disinfecting and Deodorizing Apparatus for Water-Closets, of which the following is a specification.

In disinfecting and deodorizing apparatus for water-closets whose principle of operation depends upon the evaporation of some liquid necessarily volatile, such as thymol or phenol compounds, the difficulty heretofore has been encountered that the disinfecting liquid evaporated irregularly, such apparatus when first put in service permitting its liquid to part too rapidly with its volatile components, and thus quickly becoming inefficient or of no use.

I have attained the object of a regulated evaporation by means of the apparatus shown in the drawings, of which Figure 1 is a view of the front of my apparatus, and Fig. 2 is a sectional View.

The same letters are used to designate like parts in each view.

A is a reservoir pierced by the pipe B, extending from the screw-threaded perforated cap 0 through the bottom of the reservoir, as shown. 1

D is a wick extending from the disinfecting and deodorizing liquid in the reservoir to the top of the pipe and down through the same to its outlet. The quantity of liquid escaping from the reservoir will thus be determined by the size of the wick employed.

E is a skeleton frame, preferably of wire,

in form a fan-wheel Whose vanes or floats F consist of absorbent fabric, such as lampwick, stretched upon or held by the parts of the frame E, whose axis G is supported and retained by spring-uprights H, which may be fixed to the drip-pan J', as shown, or directly mounted, as are the reservoir and drip-pan, upon a back board K. The whole may be suitably inclosed by a ventilated cover M, a

shown.

The action of the liquid as it drops from the wick D is to cause the fan-wheel E to turn periodically a quarter-revolution as soon as the Weight of the liquid received by any single vane is sufficient to overcome themertia of the wheel and the friction of its bearings. The constant discharge sets up a regular intermittent motion of the wheel, the resulting air circulation causing the complete evaporation of the portion of disinfecting liquid received by each va'ne by the time it has returned to its initial position.

I claim In a disinfecting and deodorizing apparatus, the combination of a reservoir, means for supplying a regulated quantity of liquid from said reservoir, a series of three or more absorbent vanes supported by and revolving aboutan axle, a drip-pan, and an inclosing ventilated cover.

CLAUS FREESE.
